Answer:
Card-coin experiment is a very old and widely used experiment to show the property of Inertia.
Explanation:
A card is placed on an empty glass tumbler and coin is placed on the card right above the center of the tumbler. A flick is given to the card with finger, the card flies away and the coin falls in the tumbler. It is explained by saying that due to inertia, the coin remained at its own place and the card went away due to the flick.
